Research of possibility of an assessment of the technical conditions of rolling bearings of aircraft engines through vibrodiagnostic criteria

摘要

This paper presents the experimental results of wear tests in rolling bearings. During the researches, measurements of vibration overloads were made which were subsequently analyzed depending on emergence of damages on parts of the bearings. An interrelation was established between the vibration intensity and the condition of working surfaces of parts of rolling bearings. The chalking of bearing raceways and rolling bodies lead to significant changes in the vibrational characteristics of the machine.
